Anko ListItem setOnClickListener

Question

I'm trying to play around with some Kotlin and Anko (more familiar with iOS) and taking from their example, there is this code:

internal open class TextListWithCheckboxItem(val text: String = "") : ListItem {
protected inline fun createTextView(ui: AnkoContext<ListItemAdapter>, init: TextView.() -> Unit) = ui.apply {
    textView {
        id = android.R.id.text1
        text = "Text list item" // default text (for the preview)
        isClickable = true
        setOnClickListener {
              Log.d("test", "message")
        }
        init()
    }

    checkBox {
        id = View.generateViewId()
        setOnClickListener {
            Log.d("hi", "bye")
        }
        init()
    }
}.view

My row appears how I want with a checkbox and textview. But I want to bind an action to the row selection not the checkbox selection. Putting a log message in both, I see that I get a log message when the row is selected which flips the checkbox. It does not, however, log my "test:message" from the textView click handler. Is there a way to get around this?

Apparently your issue has been addressed here. As the checkbox is consuming all the focus of ListItem you should set the CheckBox's focusable flag to false:

checkBox {
    focusable = View.NOT_FOCUSABLE
}

Unfortunately setFocusable call requires at least API 26, but you could define view .xml and inflate the view manually as described here:

<CheckBox
    ...
    android:focusable="false" />

Alternatively you could try setting a onTouchListener returning false which means the touch event will be passed to underlying views.

Let me know if it works ;)
